:PECIFICATION forming part of Letters Patent No. 714,165, dated November 25, 1902.

Application filed January 20, 1902. Serial No 90,552. (No model.)

To all 1071,0112, it may concern:

Be it known that I, EUGENE R. EDSON, a citizen of the United States of America, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Apparatus for Disposing of Foul or Ill-Smelling Vapors and Gases; and I hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in apparatus for disposing .of foul or ill-smelling vapors and gases emanating from material which is being dried or reduced or rendered.

The primary object of this invention is to prevent the said vapors and gases from contaminating the external air.

Another object is to provide apparatus of the characterindicated which is simple in construction, readily taken care of, and reliable in its operation.

With these objects in view the invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, FigureI is a side elevation, partly in section, of apparatus embodying my invention. Fig. 11 is a side elevation, largely-in central section, of a condenser which forms a portion of the apparatus. Fig. III is a side elevation in central section of a tank wherein the gases insoluble in water are separated from the soluble gases and vapors. This figure is a view looking at the side of the tank opposite to the view of the said tank shown in Fig. 1. Figs. II and III are drawn on a larger scale than Fig. I.

Referring to the drawings, y represents the receptacle wherein the drying or reduction of material from which foul gases and vapors emanate or arise takes place. The receptacle y is provided at the top with a vapor-outlet 4, which is connected by a valved pipe 5 with the water-receiving chamber 6 of a condenser a). The valve 7 of the pipe 5 is normally closed. The pipe 5 communicates with the chamber of the condenser, preferably near the lower end of the said chamber, and adjacent to the condenser has a convolution 9, arranged in a vertical plane and extending, preferably, above the condenser or at least adjacent to the upper end of the condenser, so that the passage of water from within the condenser through the said pipe 5 is avoided. The valve 7 is of course opened, if not already open, preparatory to the operation of the apparatus, so that gases and vapors arising or emanating from any material being treated within the receptacle y are conducted by the pipe 5 into the condenser.

The condenser is provided at the bottom with adrain-pipe S, which is in open relation with the lower end of the aforesaid chamber of the condenser and extends downwardly from the condenser into the body of water or liquid within a well or subterranean reservoir w, and obviously any water discharged into the condenser and instrumental in ctfecting a condensation or liquefaction of vapors and gases conducted into the condenser by the pipe 5 and any liquid forming in the condenser by such condensation pass into the drain-pipe 8 and by the said drain-pipe are conducted into the well or reservoir w.

The well or reservoir to at a suitable elevation above its lower end communicates with a pipe 77., adapted to connect with or feed a sewer, and obviously water or liquid flows from the said reservoir or well to the sewer when the water-level withinthe said well or reservoir rises to a point opposite and above the bottom of the inlet of the said pipe.

The well or reservoirw is preferably closed at its upper end by a cover 10, and the drainpipe 8 is formed by two sections joined by a union 12 above the cover 10 with the lower section extending through the cover into the said reservoir, and obviously the said cover can be readily removed upon disconnecting the said lower pipe-section from the upper pipe-section of the drain-pipe by properly manipulating and thereby rendering the union 12 inoperative.

The condenser 1s provided at its upper end and centrally with an outlet for gas and vapors not condensed or liquefied within the condenser, and the said outlet is connected by a pipe 1) with the inlet of the pump 15.

A valved water-supply pipe 13 connects with the condenser at a suitable elevation above the discharging end of the pipe 5 and has a normally closed valve 14, which is of course opened preparatory to the operation of the condenser. The water-supply pipe 13 discharges, as shown in Fig. II, into a slotted pipe-section 15, within and arranged transversely of the upper end of the chamber 6 of the condenser. The pipe-section 15 is closed at its inner end, as at 16, and embraced and supported at the said end by an annular flange 17, formed upon and internally of the casing of the condenser. The pipe-section 15, in each side thereof, has two slots 18, arranged to discharge laterally of the chamber of the condenser and extending longitudinally and from end to end of the said pipesection. Obviously, therefore, the water conducted to the condenser by the pipe 13 is discharged in sheets transversely of the chamber 6 by the water-distributing pipe-section 15 during the operation of the condenser, and upon opening the valve f the pipe 5, if the said valve has not already been opened, and operating the pump 25 a partial vacuum or suction is created within the condenser, and gas and vapors emanating or arising, from the material undergoing treatmentwithin the receptacle y and accompanying air are pulled or drawn from the said receptacle 31 through the pipe 5 into the condenser and upwardly through the sheets of water discharged from the pipe-section l5, and obviously any gases and vapors condensed or liquefied within the condensergravitate with the water discharged into the condenser into the pipe 8 and are conducted by the said pipe 8 to the well or reservoir to, as already indicated.

Gases and vapors and accompanying air not condensed or liquefied within the condenser and passing through the pipe 1; into and through The pump 15 are discharged by the pump into a valved pipe 8, which is connected with the outlet of the pump; but the valve q of said pipe is of course opened, if not already open, preparatory to the operation of the pump. The pipe 1; conducts the vapors and gases and accompanying air received thereby to a tank a, which is preferably in the form of a cylinder arranged in a horizontal plane. The chamber of the tank a is supplied with water preparatory to the operation of the apparatus, and a depth of water, having the water-level within the up per portion of the said tank, is maintained during the operation of the apparatus. The tank a is shown very clearly in Fig. Ill.

The water-inlet of the tank a-is preferably formed by a pipe-fitting b, which is attached to the bottom of the tank a, centrally between the ends of the tank, and is in open relation with the water receiving chamberin the'tank.

A valved branch 0 of the water-supply pipe 13 connects and is in open relation with the pipe-fitting b and has its valve 01 normally closed.

A valved drain-pipe 6, having its valve f normally closed, extends from the pipe-fittingb to the waste-pipe g and is attached to the said waste-pipe and to the said pipefitting.

The waste-pipe 9 extends above and below the drain-pipe 6, extending downwardly below the said drain-pipe to and communicating with the Well or reservoir to and extending upwardly above the said drain-pipe to the top of the tank a, where it (the said wastepipe g) communicates with the chamber of the said tank at one end of the tank and at the elevation of the level of Water which obtains within the tank during the operation of the apparatus.

By the construction hereinbefore described the tank a is supplied with water or drained according as the valve (1 of the pipe 0 or the valvefof the pipe e is opened; but of course the valvefis only opened when the tank a needs cleaning internally.

The foul or ill-smelling vapors and gases which are to be disposed of and to the best advantage are conducted into the body of water within the tank a during the operation of the apparatus, and such of the said gases and vapors as are soluble in the Water are absorbed into and diffused throughout the body of water and conducted OE With the water flowing into the waste-pipe g.

The valve d of the pipe 0 is of course opened and left open during the operation of the apparatus, and the supply of water to the tank a is so regulated by the valve dthat a continuous flow of liquid from the said tank into the waste-pipe g obtains during the operation of the apparatus.

Any gases and air conducted into the tank and not soluble in or conveyable off with the water flowing from the tank into the wastepipe are disposed of preferably by conducting them to the ash-pit of a furnace and there causing them to pass through the grate into the combustion-chamber next over the grate, where they are consumed and facilitate the combustion.

Fig. I of the drawings shows a furnace v1, and j designates the combustion-chamber of the furnace, It the grate, and Zthe ash-pit below the grate. A pipe m has its discharging end arranged within the ash-pit and extends from the furnace to the top of the tank a, where it is in open relation with the chamber of the said tank. The waste-pipe g communicates with the chamber of the tank a at an elevation somewhat below the inlet of the pipe m, so that there is no liability of water entering the pipe m, which extends, preferably, somewhat above the tank. The wastepipe 9 extends, preferably, into the body of liquid in the reservoir w, below the sewerfeeding pipe h, so that liquid from the said reservoir will enter and form a liquid seal in the discharging end portion of the said pipe and prevent gases and vapors which enter the said pipe, but do not enter the solution with the liquid flowing into or through the pipe, from escaping through the said pipe. Hence any gases and vapors or air received within the tank a and not carried off in solution with the water flowing from the tank escape from the tank into the pipe m, by which they are conducted to the furnace for consumption.

The means employed for introducing gases and vapors into the tank a comprises a perforated pipe-section or, arranged within and longitudinally of the lower portion of the chamber of the said tank. The pipe-section 'n is supported in any approved manner and extends through one end wall of the tank a to the other end wall of the tank, being closed at its inner end, as at 0. The pipe-section n has its lower portion provided at short intervals longitudinally of the same with orifices 'r'. The pipe-section n is connected and in open relation at its outer or receiving end with the discharging end of the pipe .5, which, as already indicated, is in open relation with the outlet of the pump t, which is shown arranged at an elevation below the tank a. The pipe 3, outside of and next adjacent to the tank a, has a convolution u arranged in a vertical plane and extending, preferably, above the tank ct, or at least above the waterlevel maintained within the tank during the operation of the apparatus, so that water cannot be conducted from the tank through the said pipe 8.

The location of the perforated pipe-section n in close proximity to the bottom of the chamber of the tank a is important, because thereby the gases and vapors are introduced into the body of water within the said chamber farthest below the outlets of the chamber, and any soluble, gaseous, or aeriform body passing into the said body of water will likely have been absorbed or diffused in the water before it reaches the said outlets, so that only gases and air not soluble in water will pass from the tank into the pipe which conducts the said last-mentioned gases and air to the furnace.

It will be observed that the pumping of the gases and vapors and accompanying air into the tank a and any suction created by a draft through the furnace materially expedite or facilitate the passage of gases to the furnace. It is evident, therefore, that by the apparatus hereinbefore described foul or illsm elling gases and vapors and odors emanating or arising from a body of material undergoing treatment within the receptacle y are successfully disposed of without contaminating the external atmosphere, and a large portion of the said gases and vapors and the accompanying air are utilized to advantage. I

would remark also that the extension of the drain-pipe 8 of the condenser into a body of water or liquid is not unimportant, because thereby water or liquid is drawn into the said pipe a suitable distance by and during the operation of the pump, and the partial vacuum or suction created by the operation of the said pump is not in errupted or interfered with, and it is obvious, of course, that the column of liquid extending into the said pipe from the body of liquid rises or lowers according as more or less suction is created by the operation of the pump.
